Illyasviel von Einzbern was a proud and experienced Magus, despite what ber youthful appearance implied otherwise. So when she heard about the Shinigami participating in the war, she thought it would be a good chance to test Berserker's power before locating and confronting Shirou. After all, even if this Shinigami was a Captain who was said to be powerful enough to take on a servant in combat, her Berserker was by far the strongest due to him being the heroic Spirit Hercules and his might was further empowered by the mad enchantment.
So to Illyasviel, at worst, this captain would be a disappointing footnote to prove Berserker's power and at best mild entertainment to properly test it.
However, what came next stunned the Master. When Berserker charged, the Shinigami effortlessly matched his frenzied blows. Kenpachi's grin widened as he parried each strike with his zanpakuto, the blades clashing in a shower of sparks.
'Well now, not bad…' he panted, his voice steady despite the intense battle. 'You have a decent amount of strength in you…' With a sudden burst of speed, Kenpachi counterattacked, his sword slicing through the air with a deadly whoosh that displaced dust and debris.
Illyasviel's eyes widened in surprise, upon feeling the air around her growing denser, and to her growing unease she realized that it was coming from Kenpachi.
'Is this...the shinigami's spiritual pressure!?' she thought in shock. 'I have known that shinigami particularly powerful ones can unleash their spiritual energy in the form of pressure to show off their power...similair to a servent using mana burst to drastically increase their strength and defense' she then gave ab uneay look over to Kenpachi.
'But this...this feels like I am being weighed down by an entire lake upon my shoulders' She pondered while struggling to stand up against the pressure. 'And if not for my mana reserves I would have passed out by now' She then however regained her composer and smiled confidently. 'But even so, I know for a fact that Berserker can beat him regardless'
The Captain then lunged at the Servant 'Let's see if that's all you can do!' Kenpachi roared, his voice like thunder.
Kenpachi unleashed a barrage of strikes, his zanpakuto a blur of motion. Berserker defended himself with his massive stone axe, each block sending shockwaves through the ground. The earth cracked and groaned under the force of their clash. Berserker roared and countered with a powerful downward swing aimed at Kenpachi's head. Yet the Captain step back just in the nick of time as the axe head bit deep into the earth mere inches from his face, which caused the groud to shatter, throwing Kenpachi off balance.
Berserker then seized the opportunity, to grab Kenpachi by the face and slamming him into the ground with bone-crunching force. Before lifting up the Captain and tossed him across the park. Cuasing Kenpachi to crash through dozens of trees, before rolling to a stop.
The captain rose, wiping blood from his mouth. 'Now we're talking!' He renewed his assault, his sword flashing in the light. Berserker parried each strike, but Kenpachi's speed and ferocity were forcing him back. The captain's blows were becoming more frequently now, each one causing Berserker to stumble. Illyasviel's smirk faltered. Her eyes widened as Kenpachi landed another blow, and even when Berserker blocked it pushed him several feet back.
In retaliation the mad heroic spirt swung his axe at Kenpachi's head. But to Illyasviel's bafflement and even seemingly to the servent's own surprise the Captain caught the stone slab with his left bare hand.
Theb within that moment of hesitation, Kenpachi thrust his zanpakuto through Berserker's throat, kiling him instantly as the Servent couged up blood the red flickering out of his eyes and falling down to the fround in silence.
'Well…that was somewhat entertaining, but I was still expecting a bit more from a heroic spirit!' The captain spat.
However just when he eas about to leave he then he noticed that Berserker's fatal wound to the skull was rapidly healing and a second later The Servant's eyes flickered back to life, before then slashing at Kenpachi, with increadble speed.
However the captain just barly manged to parried the attack and immediately countered by trying to stab the Servant's heart...but to his surprise he blade couldn't priece through Beserker's skin. Then seeing an opening the Servent tslice acorns Kenpachi's shoulder and making him bleed makinf the captain grunt and stumbling back. While Illyasviel smirked.
'You might as well give up now, Shinigami. While you may have matched Berserker in strength and skill, you can never overcome his Noble phantasm, God Hand. It resurrects him from death and makes any attack that ended up killing him useless!' She boasted smugly.
However Instead of despairing, Kenpachi's grin widened. 'Is that so?' He questioned, dodging another blow that shattered a nearby tree. He slashed at Berserker's chest, and this time, his sword bit deep into the Servant's flesh. Forcing Berserker to allow hismelf to heal his wound. .
Illyasviel's jaw dropped. 'That…is impossible! Berserker's God Hand should make him virtually immune to any attack that manged to kill him once!
Yachiru smiled and chuckled. 'You don't know Kenny, do you?' She asked Illyasviel, who looked at her confused. 'Kenny doesn't follow sanity or common sense unless it involves fighting and when he faces a challenging opponent, he always pushes himself beyond his limits. With this fight fight likely being one of his greatest challenges yet!' She grins excitedly.
Illyasviel looked over to Kenpachi and realized to her dread that the pressure the captain was releasing was increasing rapidly. Making the air around her all the more denser and for once since the first time sicne this war started she feared for the safety of her Servant as the battle raged on.
Now realizing that she had severly underestimated these Shinigami.
Meanwhile, Ichigo stood outside a barrier after patrolling around the city in his Shinigami form while his friends form a short parameter around city.
He could sense his friends and the other captains. But when he sensed Kenpachi's Spiritual power disappeared, he immediately went to the last place he felt it until he stood before a barrier that sealed off the city's park and immediately contacted Urahara wirh his soul phone given to him.
'So this barrier is some sort of bounded field?' Ichigo asked.
'Yes,' Urahara confirmed. 'It's a trademark spell of the Magi that separates the outside world within a specific arera and the affects vary depending on how the Magus themselves cast it. Though going by your description this one seems to only shield away light and sound it seems. Likely created to prevent innocent onlookers from interfering'
'Yeah…' Ichigo muttered thinking back about the times the soul socity or even rukia have gone as far as erase entire memories of humans who found out about the after life or drawing supecsion. 'And I can guess that Kenpachi is fighting a servant in there right now' he remarked.
Sado then entered the call. 'Should we help him?'
Ichigo was then nearly taken aback. "Are you crazy!?" He nearly screamed. "That guy would kill anyone who stands in the way of a fight and I'm just grateful that I am not the one fighting him this time!"
Rukia hummed in agreement from Ichigo's phone. "Well then I guess it better to leave that battle to Kenpachi while we try to lure in more Servents"
Ichigo then nodded. "Right and I will definitely let you guys know when I see Cu Chulainn"
"Copy that"Renji said from Ichigo's phone and the latter immediately put it away. But unknown to Ichigo, he was being watched by one of Rin's Jew familiars, while she was hiding behind a dark alleyway with a stern on her face while Shirou and Saber stood beside the magus.
'One of the servants and captains are already fighting against one another and there are five other individuals patrolling the area, though thankfully only one of them is on the level of a Captain, Rin explained.
'So what should we do?' Shirou asked.
"Given that they are all working together and have us outnumbered, I say we wait until they are far enough from each other and then use Saber to attack that Captain-level Shinigami while Archer and the rest of us take out the associates"
"Is that so?" A voice came from above, much to Rin, Saber, and Shirou's shock. Who revealed himself to be Uryu.
"I had a feeling that a Magus would be spying on the battle but I didn't think there would be two of them"
Tosaka then widened her eyes in shock and growled in fustration Damn it, we need to retreat now!' Rin then looked up to the sky. 'Archer!'
'On it!' The Servent responded and immediately he shot dozens of arrows at Uryu, who immediately countered by firing his own holy arrows at the projectiles and when they both collided, each of them dispersed in an explosion of sparks.
However, just as Rin, Shirou and Saber reached the end of the alleyway, they were confronted by Sado, who immediately charged at and activated his Fullbringer Brazo Derecha de Gigante and thrust his fist forward, unleashing his technique El Directo as a powerful blast of Spiritual pressure. Saber However countered by slicing through the blast with her invisible sword and charged at Sado, who then put up a defensive shield to protect himself.
Yet while the shield managed to block Saber's sword, the strength behind the servant's attack was enough to send him flying out into the streets before he managed to righten himself up and land on his feet. While Saber proceeds to carry both Shirou and Rin on her shoulders away from the battlefield by jumping on of the rooftops.
But unfortunately, Captain-level Shinigami immediately appeared in front of them with his zanpakuto over his shoulder and a second later they were all surrounded by the two other Shinigami Rukia and Renji.
And it was then that the servant and her two Masters knew have nowhere else to run.
